4080 16GB is over-priced so who cares. Anybody who would care should nevertheless NOT buy on launch day because Nvidia sets the review date line there, too. Buying GPUs blind is stupid; reviews must be read and fire hazards identified.
Instead, buy 4090 (if you need the speed), 4070 (if priced reasonably), or AMD or notebooks. 4080 16GB produced for reviewers' museums only would be ok, or Nvidia must halve the price.
Don't trust this. Ngreedia probably want to get rid of old 3000 series stock first. This fake 4080 16GB is actually a 4070 Ti at most. A true 4080 uses same die as 4090 i.e AD102
